This invention relates to car coupling devices and particularly to means for con necting ank automatic coupler with a hook coupler. Y

In accordance with the present invention, the coupling means' between the automatic and hook couplers includes two` connected shackles, one of which is freely connected with the automatic coupler and the other of which is freely connected with the hook coupler, said shackles being connected together through the medium of 4a trunnion block provided withtwo pairs of trunnions disposed at right angles to each other, one of said shackles having pivotal yconnection with one pairof trunnions and the other shackle having pivotal connection with the other pair of trunnions of the trunnion block. Y' Y f In the accompanying drawingst-f.

Figure 1 is a plan view illustratmgthe invention. Y

Figure 2 is a side view, and

Figure 3 is a-view showing the positions which the shackles may assume when the hook coupler approaches the automatic coubler.

l A portion of a car end structure is shown at l and throughtlie same, the draw bar or shank ofA an'y automatic coupler head passes,-the latter being of that type which employs a knuckle 3 pivotally connectedv with the head by a pivoted pine, and a guard arm 5 at the opposite side of the head.

lVithin the mouth 6 of the automatic coupler a pulling block 7V is located for the accommodation of means for connecting the automatic coupler with a hook coupler, the latter being represented at 8.

In the present instance, the pulling block is" shown as being formed at one end with a tongue 9 which enters the intermediate recess 10v in the free end portion of the pivoted knuckle 3. Adjacent to said tongue, the pulling block is provided'with an enlargement 11y forming shoulders which are made to'conform tothe contour of and bear against the rear face of the p'ivoted knuckle. At its other end the pulling block is formed with an extension l2 whichenters a recess or socket 13 in the guard arm of the automatic coupler head. The rearL face of the intermediate portion of the pulling block is curved or depressed so as to form a seat 1924. sel-iai No. 724,533.

14 to receive armember of the connecting means so that said member will, when in use, be disposed between the free end ofV rlhe connecting means between the pull-y ing block and the hook two shackles`17 and 18, adapted for attachment to and the former caused to ing block and be guided coupler comprises the latter being embrace the pullto and disposed 'so as to normally engage the seat 14; in said block. The shackles 17 and 18 are connected together through the medium of a trunnion block 19. A bolt passes transversely through the trunnion block 19 and pro- `iects at both ends beyond the same so Vas to provide trunnions 20-2O which receive the arms of the shackle 17 and provide pivotal connection for the same which will the hook coupler permit vertical movements of the connected l ends of the shackle. The trunnion block is provided with trunnions 21 disposed at right angles to the trunnions 20,-20 and to trunnions 21 the end portions of the arms of the shackle 18 are pivotally connected whereby the connecting shackles may have horizontal play. It is evident that instead of employing a bolt to provide the trunnions 20, the latter may be formed rigid with the block as are the trunnions 21.

The connecting devices between the automatic and hook couplers and comprising shackles connected together through the medium of a trunnion block, will operate freely and when the hook coupler approaches the automatic coupler, said connected shackles will readily assume the positions shown in Figure 3 without dangerof binding or cramping.

l/vlhen the connecting devices including the shackles andthe pulling block are not in use, they may be suspended from a hook 22 secured to the car end structure l,.as illustrated in Figure 2.

Having fully described my invention what I claim as new and desire to secure by Let-y ters-Patent, is:-

The combination with an automatic coupler including a guard arni and aA pivoted knuckle7 of a pulling block having a part to enter the guard arin and a part to engage the pivoted knuckle, a shackle having its hight engaged around said block, av trunnion block disposed between the ends of the shackle, tiunnions on opposite sides of the Jcrunnioii block engaged in the ends of the shackle, other trunnions on said trunnion block at right angles to th'e Erst-named 10 'gagged over a hook coupler.

In testirnoiiy whereof, I have signed this 15 specification.
